Abstract
A compensated temperature sensing device having a sensing element capable of surviving extreme operating environments while still being able to substantially instantaneously sense temperature changes. This is accomplished by incorporating within the device an auxilliary heat source which artificially heats the sensing gas within the sensing device. The amount of heat added to the device would be dependent upon the error in the sensed to actual temperature and the mass of the sensor which requires a change in temperature level.
Claims9
A compensated temperature sensing device comprising means for sensing the temperature adjacent thereto, said temperature sensing means including a tubular element and a gas contained therein wherein a change in said temperature alters the pressure of said gas, said altered pressure providing a first signal responsive to said temperature change, means operably connected to said temperature sensing means for providing a second signal representative of said first signal, and means operably associated with said temperature sensing means and said second signal providing means for substantially increasing the speed at which said second signal is indicative of said temperature change sensed by said temperature sensing means whereby said second signal virtually instantaneously provides an indication of said temperature change.
